Painting..... and compatibility
If my memory serves me correctly, all one-part auto type primers are lacquer based. This means you can use any lacquer, enamel, or epoxy type paint over them. I have used most of the primers on the market, both aerosol cans and spray gun, and I prefer Rustoleum gray auto primer. It has the best coverage and sanding characteristics. If your going to use a spray gun, rely on the paint store expert's directions. I've used all types of paint over Rustoleum primer and never had a problem. The only time I've ever had any problem with a primer was UltraKote and it was my own fault. I got in a big hurry and did not let the primer cure well and then used a lacquer based paint over it. Big mistake!
Hope this helps.
